No, it is already way too pedant. I'm blocking nine warnings already:

#  175: subscript out of range
#  - Ignored for broken compiler C99 support
#    e.g. tbuf[ sizeof(tbuf) ] = '\0';
                                '-wd175',

#  177: function was declared but never referenced
#  - Ignored as side effect of portability pre-processor blocks.
                                '-wd177',

#  181: argument is incompatible with corresponding format string conversion
#  - Ignored as pre-processor fails to parse variadic printf style macros.
                                '-wd181',

#  191: type qualifier is meaningless on cast type
#  - Ignored as cast required for portability
#    e.g. pgm_txw_state_t*const state = (pgm_txw_state_t*const)&skb->cb;
                                '-wd191',

#  269: invalid format string conversion
#  - Ignored with failure to display PRIu32 with (volatile uint32_t)
                                '-wd269',

#  556: cannot assign to an entity of type "void *"
#  - Ignored, it's a C++2003 error, valid in C99 aside of const
down-converting.
#    e.g. const char *s = ""; void *p = s;
                                '-wd556',

#  589: transfer of control bypasses initialization
#  - Ignored, it's a C++2003 error, perfectly valid in C99.
                                '-wd589',

#  981: operands are evaluated in unspecified order
#  - Ignored as pedantic warning against possible side effects.
#    e.g. printf ("%s.%s > ",
#                 pgm_gethostbyaddr((const struct in_addr*)&ip->ip_src),
#                 pgm_udpport_string(pgm_header->pgm_sport));
                                '-wd981',

# 2259: non-pointer conversion from "/type a/" to "/type b/" may lose
significant bits
# - Ignored for really pedantic compiler temporary value conversions,
#   e.g. uint16_t j = 1, i = ~j;
                                '-wd2259',
